Tax Optimisation

Reducing your tax bill, intelligently

Reducing tax is never an end in itself. The right instinct is to look first for an investment that makes economic sense, then identify the tax scheme that makes it more efficient. Doing it the other way round leads to buying economically poor products for a few thousand euros of tax savings.

Overall cap

€10,000/year

Overseas territories cap

€18,000/year

Outside the cap

PER, Malraux, déficit foncier

Worthwhile from TMI

30%

§ 01

The golden rule: tax savings do not equal profitability

An 18% tax reduction on an investment that returns minus 25% is not a good investment. The question to ask is never 'how much will I save?', but 'does the underlying asset stand on its own without the tax break?'.

§ 02

The schemes that actually work

In order of robustness for most high-TMI profiles:

  • PER: a universal, flexible deduction tool, with unrestricted withdrawal since 2019
  • Déficit foncier (property-renovation loss offset): very powerful for owners of older properties needing renovation
  • Girardin industriel: a one-off tax reduction, to be handled only with a solid counterparty
  • FCPI/FIP (innovation and regional investment funds): 18 to 25% tax reduction, but disappointing historical performance on average
  • Malraux / Monuments Historiques (heritage building schemes): for substantial estates, on exceptional properties

§ 03

The overall cap on tax loopholes

€10,000 a year for most schemes (€18,000 including Girardin / Sofica / overseas investment). This cap fills up quickly for high-earning households, which makes prioritisation a strategic exercise.

§ 04

Schemes outside the cap: the ones worth knowing

PER, the Malraux law, déficit foncier, and Monuments Historiques: these levers do not count towards the overall €10,000 cap. For a household that has already maxed out its cap, these are the real remaining levers.

Frequently asked questions

What I get asked most.

Which scheme is the most profitable?

There isn't a single answer: it depends on your TMI, your horizon, your existing assets, and your risk tolerance. The PER is the most universally relevant option above a 30% TMI.

Should I reduce my tax every year?

No. In some years, nothing is worth doing. Forcing a mediocre tax scheme just to 'do something' is often the worst decision you can make.
